Capacitive performance of electrodeposited PEDOS and a comparative study with PEDOT
چکیده انگلیسی


- PEDOS was investigated as a novel and active supercapacitor electrode material.
- PEDOS film electrode afforded good specific capacitance.
- The different capacitive performance between PEDOS and PEDOT were explained.

Poly(3,4-ethylenedioxyselenophene) (PEDOS) prepared via electropolymerization was investigated as an active electrode material for supercapacitor in 0.1 M CH3CN-LiClO4. Meanwhile, Poly(3,4-ethylenedioxythiophene) (PEDOT) as a contrast was prepared and measured under the same conditions. The resultant polymers were characterized by EQCM, FT-IR, SEM, CV and EIS. Although EDOS possessed higher molar mass which may result in lower specific capacitance in theory, but the higher doping level (y = 0.53) make the specific capacitance of PEDOS over that of PEDOT. Based on this, PEDOS has the potential to become a good supercapacitor material. The compact PEDOS electrode afforded a higher specific capacitance of 208 F g−1 at 25 mV s−1 compared with PEDOT (205 F g−1). Furthermore, the specific capacitance of the symmetric full cell based on two PEDOS electrodes reached 42.02 F g−1 at 25 mV s−1.
